P&O accessible excursions v Private tour!

Last week I received from P&O's shoremobility a list of the wheelchair accessible excursions for our cruise A615 to the Baltic in June onboard Azura and I have to say that I was very disappointed by the number on offer and the selection but not surprised.  In total there are 11 accessible excursions for the whole cruise compared with 88 standard excursions and I am sure that could be improved. I find it hard to believe that Norway, Denmark. Sweden and even Russia do not have accessible minivans or coaches that can be hired, after all what do their own disabled people do.  One port that I was sure would have excursions was Zeebrugge, Belguim but they only offer a continuous shuttle service
from the pier to Blankenberg and will run with train schedules. 

Ghent, Belgium

The shuttles will drop off at the train station where passengers can then decide to take the accessible train service onto Ghent, Bruges, Brussels or visit the city centre.  
The information regarding accessible shuttle services at other ports is unknown and won't be known until onboard ship.  Sometimes it feels as if disabled people are not wanted on cruise ships; an inconvenience comes to mind.  It really does annoy and frustrate me the way these cruise lines think it is acceptable to charge disabled passengers anything upto 150% plus for accessible excursions that are the same as the standard excursions.  I do understand that it is probably going to be more expensive to hire an accessible vehicle but not hundreds more.  I personally refuse to pay hyped up prices.
For the above reasons we decided to look into a private tour of St Petersburg with Guide Guru and we have been able to tailor the tour to suit my pace and earlier this week we had it confirmed and the day tour goes as follows: 
8:00am - Meet our guide at cruise teminal 
8:30 - 11:30am City tour and visit inside Spilled Blood Church
11:30am - 12:30pm Visit St Issac's Cathedral
12:30 - 1:30 Lunch & free time 
2:00 - 4:00pm The Hermitage & Winter Palace 
4:30 - 5:30pm The General Staff Building to view French Paintings of 19th & 20th Century
5:30pm Shopping before returning to the ship at 6:30pm.   
Being private we have been able to see things that are important to us such as the paintings and leave places like the fountain park for others to enjoy, I have a phobia of fountains.  We consider the price to be fair for what we are getting.  It is far cheaper than a half day private tour that P&O can arrange.  
Being disabled can be challenging at the best of times and being a partial wheelchair user like myself who uses other aids you often feel as if your needs are not taken into consideration.  In the information from P&O it clearly states that accessible minivans hold three wheelchairs and three companions.  Nothing in this literature mentioned walking disabled.  
I glad that we have booked a private tour because I will be able to do things at my pace and not worry about anyone else.
